The BP gas station near 40th and Dodge was robbed at 3:24 p.m., dispatchers confirmed, and the BP gas station near 24th and Martha was robbed at 3:56 p.m.

"The guy came in, pulled a gun," Jacob Patterson, a clerk at the 24th and Martha gas station, said. "My manager came in and saw him. The guy ran out. He got away with some money. A drawer full of cash."

Dispatchers confirmed that a black man with a weapon entered the stations and demanded money before fleeing the scene.

Authorities searched the area near 21st and Martha for the person responsible after receiving information that the man may have entered an abandoned house.

Three stores were held up on Nov. 2 and a store on Sunday; police believe the same man could be responsible for those robberies.

"Everything from both robberies seems like it's consistent that it would be the same suspect," Officer James Shade said.

A K-9 checked the house but didn't find the man, according to a release from the Omaha Police Department.

Able-1, OPD's police helicopter, also responded to the location.

The man is approximately 5 feet 8 inches tall, and was wearing a black cap and blue sweatshirt with four white lines on it. The sweatshirt is possibly Echo brand.
